| | A role is a collection of permissions defined for the whole system that you can assign to specific users in specific contexts. The combination of roles and context define a specific user's ability to do something on any page. The most common examples are the roles of student and teacher in the context of a course. |
| Roles are groups of permissions. Users are assigned roles in specific [[Context|contexts]]. The combination of roles and context define a specific user's ability to do something on any page. The most common examples are the roles of student and teacher in the context of a course.

| :'''Note:''' Sometimes the terms "capabilities" and "permissions" are used to mean "the ability to do something". Technically, they are different. A capability is an action created in the code (edit a quiz). Permissions are assigned to the capability.

| | *[[Using roles]] |
| ;Role
| | *[[Standard roles]] |
| :An identifier of the user's status within each [[Context]]. The status depends upon permissions given for one or more capabilities in any given context. A role can often change within different contexts.
| | *[[Creating custom roles]] |
| ::For example Teacher and Student are standard user roles. These roles probably have different capabilities in some contexts but may share permissions in the other.
| |
| :When Moodle is first installed, a number of [[Standard roles]] are created automatically.
| |
| ;Capability
| |
| :A description of a particular Moodle feature. A list of many capabilities can be seen in the [https://docs.moodle.org/en/Category:Capabilities capability category index page].
| |
| ::For example [[Capabilities/moodle/blog:create|moodle/blog:create]](writing blog entries) or "Backup course" are two capabilities.
| |
| ::Note: the "<nowiki>mod/blog:create</nowiki>" notation is a common to identify a capability.
| |
| ;[[Manage_roles#Permissions|Permission]]
| |
| :A setting for a capability. Can be any one of four: not set(inherit), allow, prevent or prohibit.
| |
| ;[[Context]]
| |
| :A "space" in Moodle.
| |
| ::For example: a course, activity module or block can each be a context.
| |
| ::Some contexts can contain multiple contexts in their space. For example, a course can contain a lesson, assignment, forum and quiz modules, plus blocks.
